The trivial fiber topology and framed motives over the integers
A. Druzhinin, HÃ¥kon Kolderup, Paul Arne Ãstvær
This paper introduces the trivial fiber topology on schemes. For one-dimensional base schemes, we use it to describe fibrant replacements in the stable motivic homotopy category an…

A symmetry approach to number tricks
HÃ¥kon Kolderup
We generalize the classical "1089-number trick", which states that a certain combination of addition, subtraction and swapping the digits of a three-digit number will always output…

Hermitian -theory and Milnor-Witt motivic cohomology over
HÃ¥kon Kolderup, Oliver Röndigs, Paul Arne Ãstvær
The theme of this paper is to compute hermitian -groups in terms of the recently developed theory of Milnor-Witt motivic cohomology. Our approach makes use of the very effective…
